What valve springs? Just curious.
I couldn't find the folder on the valve spring info but they were matched for the erson cam. I believe 1 coil spring no dampeners.What valve springs? Just curious.
here is the video of the erson cam in the 273 with flat top pistons . sounds "Nasty" with low compression .. cold start up .
upon doing more research on these 1 3/4" fenderwell headers ... I think they will not be a good choice for the 273 .. may take away alot of bottom end power away . I think the sweet spot is 1 5/8".Going to use hedman husler p/n 75109 fender well headers . 1 3/4" tubes with 3 inch collectors with this new "Beast" . Same 1 3/4" size tubes were used on the 66 d-dart. I think they should make some serious hp. not too small, not too big , Just right !
Oh man...what are the 318 guys going to do now ... start a "which is better " thread about the 273...?
even with low compression flat tops it has a nice pop to it .That thing sounds strong!
Low compression motors can run really strong if tuned right. That's pretty much the secret to making most any combination run is the tune. A crappy tune will make even the best combination shine like a rusted blade.even with low compression flat tops it has a nice pop to it .
no ..............this 273 has the 10.5 dome pistons. this engine makes way more hp and tq than the (erson) big cam did. this 273 "SCREAMS" !!That sounds a little tammer than the Erson cam. Still has a lope. Is this engine low compression 273?
LOL .... believe or not, snow tires do GRIP !I quess i missed the part of naming the Beast.
Does it have anything to do with the off-road equipment tires? Sounds like one hell of a "FABO Dune Runner" Go Bro Go ;)
I asked the owner what kind of numbers it turned but no response.
Sounds good though.
I asked 3 years ago and no response. Let's say 275- 300 horse @5500 rpm. LOLSweet ! hope the owner gets back to you of dyno results !
